Real-Time Rendering - The guidebook. Excellent for getting a lay of the land and figuring out what specific papers/technologies/techinques to look into. The book’s bibliography alone is invaluable.
Learn OpenGL - Great tutorial series. Great companion to have with Real-Time Rendering for actually implementing features/techniques.
Learn WebGPU (C++) - Super in-depth tutorial for learning about WebGPU and computer graphics in general. I was able to use this tutorial and go straight to Rust’s wgpu library too with very little friction.
Kosmonaut’s blog - Doesn’t look like they post anymore but still a treasure trove of posts. Their series on building a deferred renderer really helped me out with my renderer oceanman.
Evan Chen’s website - tons of Math Olympiad resources and An Infinitely Large Napkin, which covers a metric ton of higher math topics/concepts. Super fun to browse through!
